TEST CONDITIONS
Max voltage to ensure the converter is
disabled
2.375V ≤ VIN ≤ 5.5V
5.5V < VIN
VIN = 5.5V
Threshold voltage for Logic Low
Threshold voltage for Logic High
(internally pulled high; can be left
floating to achieve logic high)
(VIN = 5.5V)
VSx = GND
VSx = VIN
VSx = Open
IPOK = 4mA (sink current)
